Can't see anything...that's why. You have the coin lit from the side, a bad position for trying to show doubling. The lighting needs to be flat onto the surface of the coin shadowing the sides of the devices. The picture also needs to be far closer to the coin - you need to be using a microscope for your image.
With it backed away to that level it would have to be a major doubled die to be visible, and I don't see anything in the photo provided.
